In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called The catalytic addition of alkyl boranes to alkynyl esters affording single-isomer trisubstituted olefins, published in 2011-05-12, which mentions a compound: 58656-04-5, Name is Tricyclohexylphosphonium tetrafluoroborate, Molecular C18H34BF4P, Formula: C18H34BF4P.
The generation of a series of trisubstituted olefins bearing alkyl substituents was described using a stereo- and regioselective addition to alkynyl esters. The method produces trisubstituted olefins as single isomers using a convenient and mild transformation in which alkyl boranes are cross-coupled with alkynyl esters and amides using Pd catalysis.
From this literature《The catalytic addition of alkyl boranes to alkynyl esters affording single-isomer trisubstituted olefins》,we know some information about this compound(58656-04-5)Formula: C18H34BF4P, but this is not all information, there are many literatures related to this compound(58656-04-5).
